A model for tar-removal efficiency from biomass-produced gas impinging on a water surface

Prediction of venturi scrubber efficiency used in an updraft gasifier cleaning train

“…However, one of the major problems of using the biomass gasification is the contamination of the producer gas with tar vapour. The tar in the gas has been found to gum up the moving parts of the engine, necessitating thorough cleaning of the gas before it is introduced to the engine (Cruz, 1980(Cruz, , 1991Khummongkol, 1989;Parikh et al, 1991).…”

“…During operation, almost all of them faced the problem of tar removal. Although attempts have been made to remove tar from the product gas using a spray column (Cruz, 1980), an oil venturi (Graboski and Brogan, 1988), fabric filters (Khummongkol, 1989), packed bed filters made from rice husk (Khummongkol, 1989), an electrostatic precipitator (Nonhebel, 1964), gas impingement on a water surface (Khummongkol, 1989), and a bubble cap 0363-907X/92/08073 1 -1 1 $10.50 0 1992 by John Wiley & Sons, Ltd.…”

Catalysts and catalytic processes for the transformation of tars and other non-conventional feedstocks into fuels and chemicals

“…The most common types of wet scrubber are packed column scrubber (spray tower), venturi scrubber, packed bed scrubber, and impingement scrubber [50,56,86,87]. Several publications have reported the use of these types of wet scrubbers [94][95][96].…”
